Y but preferably slightly in advance in point For the purpose of a clear and definite of time and at an angle and preferably description of my invention I have herein 90 tegral therewith. However, when a t1e shown in the drawings apparatus for carry-v plate is to be formed with both the trans vi ng out or practicing my process or method verse shoulder or rib member on one side without intention of limiting myself to such and a fiangeor flanges on the opposite side, apparatus, and I will now proceed. to dosome measure of 11:5 invention may be ob scribe my method in connection with such tained by subjecting the body portion of the I apparatus. blank to a. greater percentage of reduction 1 As herein shown, reducing rolls are prothan the flange'portion thereof and then vided comprising an upper roll Z1 and a relieving the pressureupon the body porn lower roll c whim are rotatably mounted in tion by resenting to itthe transverse slot I suitable bearings (Z in a supporting .iramc c in one 0% thefreducingfrolls, it bcin under- I of the ordinary and well known construcstood that the flange or flanges referred to tion. The lower roll is provided with an,

run in the! general direction of the blank nular peripheralgrooves f for- .t'orming the and at'anangle to the shoulder and are longitudinal 'bottoni flanges g ofthe t1cpreliminarily formed or practically so in plates when such flanges are to'be used.

order that such difference; in the draft or amount of reduction between the body P01? tion and the flange portion "will'take place as described. It will be llHCiBfSt-OOd that a series critic-plates is formed from a single he upper roll is provided with longitudinal peripheral slots 01" grooves 71 for form- .ing thetinnsvcrse shoulders or ribs 2' which engage the rail and which by preference,

though not of necessity, extend all the way across the plate.

with the result that in the rolling of the blank. according to my process the bosses or reinforcements ]t' and Z are formed integral with the transverse shoulders z, the particular portion 70 of the boss, alfter severingof the blank into tie-plate lengths, belonging to the next adjacent tie-plate, as clearly indicated in Figs. 8 and 9. 1

Now referring more particularly to the practice of my process in connection with the described apparatus, the blank or strip a of metal is passed between the rolls preferably in the direction indicated by the arrows in Figs. 8 and 10, although it is possible that the strip-may be passed therethrough in the opposite direction. The blank or strip -is thereby subjected to the reducing action of that the tie-plates'are to be provided with bottom flanges which are substantially completely formed prior to the arrival of the blank 'at the rolls 7) and 0, the body portion of the blank is subjected to a greater percentage of reduction than the flanged portion thereof, due to the prior substantially complete formation of the bottom flanges, and thereupon, according to my new process, this pressure of reduction upon the body portion is relieved by presentingto it a transverse slot it so as'to form the transverse shoulder or rib i. taneously and preferably sli htly in advance of the formation of t? shoulder the pressure is materially relieved by means of the recesses 72/ which are arranged to form the bosses adjacent the transverse shoulder with the result that the distortion of the plate during the formation of the rolls to become banked'up somewhat of the shoulder is prevented and the resulting tie-plate'considerably strengthened. By preference the blank is fed through the rolls in a direction at an angle, .ri ht angle, to the transverse shoulder, in all cases these bosses being arranged at an angle to said shoulder. In passing through the rolls the plate is thus subjected to gradually changing or decreasing pressure substantially during the time of formation of the transverse shoulder preferably in ad- Vance thereof by forming the longitudinally extending boss or bosses. The described reducing pressure-causes the metal in advance and the admission of such metal under pressure into the recess and slots described,

materially relieves said pressure and at the same time the desired construction of tieplate is produced. It is preferred to employ the recesses h both to secure a reinforced tie-plate and to bring about a material relieving of the reducing pressure, preferably such a manner the rolls and in the event Substantially simul- 1e, transverse preferably at ain a gradual manner, so that the transverse shoulderwlll be formed without, any danger of distortion of the plate. However, as hereinbeforestated, when the bottom flanges are:

employed a difference in draft or percentage of reduction upon the body portion of the plate and the an'ge portion is, obtained in that the transverse shoulder is properly formed'without distortion of the plate. WVhether the plates are provided with a flange portion or projectionv of any kind on the bottom s de or not, the relievin of pressure in the or'of the boss, or of the shoulder and boss together, is sufficient to maintain the upper orbearing surface for the rail substantially straight, said ,-relie v ing of pressureon such upper surface taking place without a cor responding relieving of pressure on the other or lower side thereof. It will be understood that any desired number of passes may be employed for the complete formation of the plates, the particular rolls herein. shown being the so-called finishing rolls, it being unnecessary to show the earlier rolls for reducin this billet or other piece of metal to strip or blank form. The resulting strip.

contains a series of tie-plates and is then severed or otherwise divided into tie-plate lengths as indicated by dotted lines in Figs.

8 and 9, each section or plate being a shouldered and reinforced tie-plate. The tieplates are thereupon perforated or punched .to form the spike holes m and n and spikes such. as the screw spikes 0- having annular spike heads or shoulders p and squared ends 9 are mounted in the" spike holes with the spike heads or shoulders in engagement with the bottom flanges 1" of the'track rail 8 and with the outer bottom faces of said s ike heads or shoulders resting upon the top aces of the reinforcing bosses 7c and Z, respectively. The tie-plates thus formed consist 'of a main body portion 2% having bottom flanges g which are here shown as. longitudinal, a transverse shoulder or rib for engaging the bottom flange of the rail, and longitudinal transverse rib and extending therefrom to its end of the plate. However, as indicated in Fig. 7 the bottomflanges may be omitted but the top face of the plate may be however provided with both the transverse shoulder and the bosses. Thus by the practice of my invention I am enabled to roll perfect and undistorted tie-plates in a simple and economical manner by subjecting the blank .01? strip .to the reducingaction of the rolls and properly relieving the reducing pressure in a novel manner and at the same time producing formation of the shou der bosses 70 here integral with the g a tie-plate of an eflicient and desirable construction.
